Application filed May 5,1884. (No model.)

To all whom it may concern.-

Be it; known that I, JosEPH (J. BROWN, a citizen of the United States,residing at the city of Burlington, in the county of Ohittenden andState of Vermont, have invented certain new and useful Improvements inan Apparatus for Automatically Mixing, Measuring, and DeliveringPowdered Material into Packages, of which the following is aspecification, reference being had therein to the accompanying drawings.

My invention relates to improvements in an apparatus for automaticallymixing, measuring, and delivering into suitable envelopes or packagespowdered material of any character;

- and the objects of my improvements are, first,

to provide an air-tight receptacle to contain the powder,where it can beproperly agitated, thoroughly mixed, and then delivered into themeasuring device without exposure to the operator or to inconvenience orloss of the material from air-currents; second, to facilitate a rapidand reliable measurement of the quantity of powder desired to be put upin suitable packages while properly protected from the air; third,todeposit the material thus measured and guarded from air-currents intoenvelopes or other suitable packages prepared to receive it; and,fourth, to automatically deliver the packages for filling, and thencecarry them to a place where they can be properly closed and arranged forcommercial purposes. I attain these objects by the mechanism illustratedin the accompanying drawings, in which Figure 1 is an elevation of myapparatus, the dotted lines in the interior of the receiver indicatingthe form and position of the mixer, scraper, and the application of themotive power. Fig. 2 is a plan view showing the 7 relative positions ofthe motive power, re-

ceiver, and the turntable to which the packages are attached. Fig. 3 isa side elevation of the measuring device. Fig. 4 is a side view of oneof the arms designed to retain and subsequently deposit thepowder-packages when ready to be sealed. Fig. 5 is a plan view of theapplication of the motive power to the turn-table. Fig. 6 are elevationsof the tunnels which are employed to direct the powder into thepackages, the form of their lower extremities varying according to thequantity or character of the material to be passed through them. Fig. 7is a detached View in perspective of a portion of the interior of thereceiver, showing the revolving diaphragm or scraper, its attendanttrowel, and the motive power. Fig. 8 is an enlarged detail view showingthe scale in a different position from what it is in Fig. 1. Fig. 9 isan enlarged view of the bottom of the receiver. Fig. 10 is an enlargeddetail view.

Similar letters indicate similar parts throughout the several views.

A is a circular receiver,preferably made of metal and surmounted by acover for the purpose of protecting its interior from air-currents. Itis intended to contain the powder to be mixed, measured, and thenconveyed to the envelopes or other packages designed to receive it. Itis sustained at a suitable height above the floor or table by themetallic bracket B, which also forms the base of the standard whichsupports thelying shaft 12, by which power is transmitted from thepulley a through the miter or bevel wheels 0 d to the central or uprightshaft, 6, which passes down through the receiver and rotates both thediaphragm or scraper O and the revolving disk or camD beneath thereceiver.

E is a metallic cone, which is located in the center of the receiver andextends from the bottom of the receiver, to which it is attached, to therevolving arm f of the diaphragm 0.

Attached to the exterior surface or circumference of the cone E, abouttwo inches above its base or the bottom of the receiver, is a flangeorhorizontal projection, g, which extends outward from the cone nearlyto the sides of the receiver, so that only a narrow open space is leftbetween the outside edge of the flange and the sides of the receiver A.Its

purpose is to sustain the weight of the powder contained in the receiverabove it, and allow free movement to the semi-disk, which rotates on thebottom of the receiver below it, and thus prevent the powder frompressing down too heavily into the opening is in the bottom of thereceiver, thereby securing a uniform delivery of the powder into themeasuring-box F, into which the aperture 75 opens. The diaphragm orscraper 0 stands vertically,

and is of such shape as to fill the space within the receiver above theflange g, as it revolves on the shaft 0. Its lower part being turnedsomewhat backward from the line of its upper arm, f, it exerts acontinuous and drawing force upon the powder deposited upon the flange,thereby crowding it continually towhich falls onto the bottom of thereceiver clinging to the under side of the flange through the open spacebetween the edge of thefla'nge g and the side of the receiver into theopening is, Fig. 2, in the bottom of the receiver, from whence it passesinto the measuringdevice F.

At the. rear end of the traveling disk 6 is a trowel, Z, which extendsupward from the disk, for the purpose of preventing the powder from gand on the sides of the receiver.

The measuring device F, Fig. 3, consists of a box or vessel having twosides and rear end closed and immovable. It is rigidly attached to thetop of a reciprocating lever or rod, G, which is pivoted to the standardW at m. Its bottom being connected with the slide j, which has avertical movement on the lever G, controlled by the adj Listing-screw n,can be set at any position indicated on the scale J, and there held bythe set-screw o. By this arrangement the boxF can be made of any depthdesired, and its capacitycorrespondingl y regulated according to thequantity designed to be deposited in each envelope or package. The frontend of the box is so hinged at its bottom that it can be readily droppedforward by pressing back the bar 19, which is connected with it, andprojects below the bottom of the'box suiiiciently far to hold the end ina vertical position, and thus close the box by the force of the springq. The rod or lever G has a reciprocating motion caused by its extensionbelow its pivotal point at such an angle that it shall always impingeupon the periphery of the cam D by reason of the contracting force ofthe spring-r, which connects it with the receiver. During the time thatthe lever G presses against the regular circubottom of the receiver.

lar part of the cam the box F remains in an K is a semicircularprojecting guard or cover attached to the bottom of the receiver A. It

is designed to cover the box F as it moves from the opening in thebottom of the repowder can pass out. covering the opening the box ismoved so as to discharge its contents, and then receiver to the tunnelH, so as to protect the contents of the box from air-currents and form aguide to direct it into the tunnel.

to is a stationary pin, which is rigidly at tached to one of the underedges of the guard K and near its lower extremity. Itis angular in formand extends back toward the receiver so as to come in contact with andpush back the spring-bar p, which is attached to and pro jects below theouter or hinged end of the box F, as the box is tipped forward by reasonof the pressure of the lower end of the lever G against the recessedportion of the periphery of the cam D, and thus bycausing the hinged endof the box F to lie in the same plane with the bottom of the box allowthe contents of the box to readily pass into one of the tunnels H assoon as it is reached by the box F.

The measuring by the box F is performed as follows: The depth of the boxhas first to be adjusted according to the quantity of the powder desiredto be deposited in the envelope, for the disk twill crowd into theopening 70 all that the box will hold. The depth of the box F isregulated by moving its bottom up or down on the slide j, which has avertical movementon the lever G, and which bottom is fastened in placeby a set-screw, n. As soon as the box F is filled it is moved toward thetunnel and envelope which is to be filled. On the scale J aremarksindicating the weight of the powder in the box according to theposition of the bottom of the box. No matter what the position of thebottom may be, the disk 2' will force enough powder through the opening70 to fill the box, and then the disk covers over the opening it, sothat no more While the disk is still turns to position again, ready tobe again filled. These tunnels are attached to the outer extremities ofthe radial arms I, which, by a simultaneous movement, hereinafterdescribed, are brought to a position in front of the guard K at the samemoment that the box F is tipped forward to discharge its contents intothe tunnel and thence into the envelope or package which has beenpreviously placed upon the pack age-support V of the perpendicularspring w, which is attached to the arm'I. This package-support projectsforward in nearly a horizontal direction, and is firmly attached to thevertical spring w and sufliciently below the lower extremity of thetunnel H to permit the package or envelope, which it is designed tosustain during the act of filling, to be placed upon it in such aposition that the lower 'extremity may readily enter it. The package isheld upright by the face-plate U, which projects downward from the endof the arm I, to which it is firmly attached. Near its bottom is anopening to allow the package-support V to pass through, the object beingto sustain the package on this support until the spring w is forced backby being brought into conaround the standard R, in the mannerhereinregular circular periphery of the cam Dduring its rotation,reaches the square notch s in the recessed portion of .the cam. Thesudden dropping of the lever G into the notch s has once drops to thetable T below, whence it can time another opportunity is given to theop- J319,672 I z;

tact with the upright bar S at. the endof the i reciprocating rod Q asthe. arm I is carried aftertdescribed. By the withdrawal of the supportV 'through the faceplate U, by the pressure of the bar S against thespring w, the package, being deprived of its support, at

be removed at pleasure. When the box F reaches the tunnel H, the lowerend of. the lever G, which has been pressing against the the'effect toproduce a sharp striking motion on the lever, and therefore to the box Fon its upper extremity sufficient to entirely empty the box of whatevermight otherwise be retained. As the cam D continues to rotate, thecontracting force of the spring 1 keeps the lower end of the leverimpinging upon its edge, gradually returning it again to the circularregular portion of its periphery. The effect is to press this end of thelever G forward and the upper end of the lever correspondingly backward,until the box F is again brought into its former horizontal positionbeneath the opening in the bottom of the receiver A ready to be againfilled with the material, which during this time has been conveyed tothe opening is by another revolution of the diaphragm O, and theconsequent rotation of the disk t within the receiver. At the sameerator to place another envelope or package upon the spring-support ofthe next arm I, which is meanwhile approaching the deliverypoint, readyto be filled from the next tippingforward and emptying of the box F, asbefore described.

J is a horizontal rod pivoted to the reciprocating lever G at 2. It issustained by suitable bearings, and has a horizontal reciprocatingmotion by reason of its connection with the lever G, and is design'ed,bymeans of the spring-pallet L, Fig. 5, to act upon and give anintermittent rotation to the wheel M,which has as many ratchets in itsperiphery as there are arms I.

t is a verticalshaft of the pinion M,to which it is attached, designedto convey to the top plate, N, a motion corresponding with that of thewheel M. To this plate N the radial tunnel-arms I are pivoted at w.Directly below the plate N is a circular stationary plate, 1?, supportedby the frame It, through the center of which passes the shaft t. Theupper surface of the front half of the plate I? is dentated, so that asthe tunnel end of the pivoted arms I are carried over it by the rotationof the plate N the shoulders, which rest upon the stationary plate P,pass over the dentations and successively drop into each interdentalspace, thereby causing the interior extremity of the arm I to strike theunder side of the plate N, and thus cause an abrupt forcible jar to thewhole arm,which thoroughly shakes and empties each tunnel into thepackage beneath it, from the moment the tunnel is filled from thereceiver until the package is removed by the upright bar S, which isplaced on the outer extremity of the rod Q in such a position that asthe rod is carried back toward the receiver by the entrance of the leverG into the recessed portion of the cam D it pushes back the spring w andwith it the support V which sustains the package. The package orenvelope being thus deprived of its support at once drops upon the tableor platform T below it, whence it can be readily removed by the operatorto the movable slide Y as fast as it is deposited. As there is nooccasion for jarring the arms I afterv the removal of the packages anduntil they are again replaced to be filled,the upper surface ofthe rearhalf of the plate P is smooth. 7

Thus constructed,the entire ap paratus after the the material has beenplaced in the receiver A causes the powder or material to be thoroughlymixed in the receiver, and then to be reliably measured, according tothe quantity desired to be put up, and then deposits that quantity intoan envelope or other package without any effort or care of the operator,except to keep the receiver A supplied with the material to be mixed andput up, and the packages or envelopes removed from the table T, and newones supplied to the arms as fast as it becomes necessary, and at thesame time the person of the operator is effectually protected from allinconvenience or injury resulting from any flying dust from the powder,as

no air-currents can affect or reach the powder after the top of thereceiver is closed.

The several movements of thedifferent portions of the entire apparatusare automatic and uniform on account of the peculiar construction andmutual interdependent arrangement of its parts.

What I claim, and desire to secure by Letters Patent, is-- 1. Thecombination of a receiver for the powdered or other material, arevolving shaft extending into it, a revolving semi-disk which forcesthe material through an opening in the bottom of the receiver and thencovers or closes the opening to prevent the escape of the material afterthe box is filled, and the movable box which receives the material anddelivers it to the package which is to be filled, substantially asshown.

2. The combination of the receiver, the revolving shaft, revolving conecarrying a disk cone and suitable outlet, in combination with a rotatingdiaphragm, G, and (semi-disk i, j:
